I'm probably the first person to ever have trouble getting the rollpin back inside the carrier to hold the pinion shaft - I hope not. I've got the front carrier and Lockrite re-assembled and couldn't get the rollpin back in to save my life. After breaking all the tools that I shouldn't have been using in the first place the rollpin made it about a quarter of the way in before breaking. Everything I've read didn't mention that being a problem at all. Anyway, is that rollpin something NAPA would carry or is there a reliable replacement? Lastly, was that supposed to be pressed in? I can't understand why it was so friggin' tough to install.
